Hi BSGSV,
Many thanks for your interesting post.
"The carriage numbers Mr. Mundy took pics of at Antrim on 28/10/67, that I have are":
Lined: N384 (ex-GNR K 13, UTA stock classification 'A' - withdrawn 1970), N464 (ex-GNR L 9, UTA stock classification 'A' - withdrawn 1969), 338 (ex-NCC J 12, UTA stock classification 'B' - withdrawn 1969), 342 (ex-NCC J 12, UTA stock classification 'A' - withdrawn 1975), 375 (ex-NCC J 11, UTA stock classification 'A' - withdrawn 1969).
Unlined: 291 (ex-BCDR type 5, UTA stock classification 'A' - withdrawn 1969), 230 (ex-NCC I 3, UTA stock classification 'B' - withdrawn 1969), 385 (ex-NCC J 11, UTA stock classification 'A').
As you can see from the above (assuming the all the relevant carriages numbers are correct), three examples blow my contention about lining being restricted to only 'A' classified stock out of the water! Many thanks for taking the trouble to post. I would rather be corrected than live in mis-assumption!
